Hi Steve, TEP 126 must be incorrect - I documented that information based on someone else's experiences with enabling encryption, not my own.
A layer that enables hardware encryption would be extremely beneficial to the TinyOS CC2420 stack. If you're interested in pursuing this functionality, let's see how we can get it designed and integrated as an optional layer in the CC2420 stack. -David -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steve McKown Sent: Wednesday, June 06, 2007 8:29 AM To: tinyos-help@Millennium.Berkeley.EDU Subject: [Tinyos-help] TEP 126 and AES Hi, TEP 126 in 10.1 states that the CC2420 radio cannot begin encryption at a particular offset. However, v1.3 of the CC2420 data sheet in section 21.5 specifically states that this is possible, via the SECCTRL1.SEC_TXL and SEC_RXL register fields. Does the comment in 10.1 come from testing real parts, reading an older spec, etc.? PS - We have a project for which we plan to use CC2420 CCM with a 32-bit MIC which will start in earnest in the next few weeks. I would be interested in learning how our efforts in this regard can best be coordinated for possible inclusion into the new CC2420 stack. If someone is already working on this, perhaps we can collaborate.
